To (1N whom t may. concern:

Be it known that I. Louis F. HAGEMAN, Jr., a citizen of the UnitedStates, residing at Niagara Falls, in the county of Nlagara. and Stateof New York, have invented certain new and useful Improvements inApparatus for Treating lVebs. of which the following is a full, clear`and exact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to an apparatus for treating webs of paper andwith regard to certain more specific features thereof, to the treatmentof continuous webs adapted for use in recording machines, sales books,and the like.

One of the objects of this invention is to provide a practical andefficient mechanism or apparatus for treating 'and folding a web wherebyit may be subsequently used 1n recording machines, sales books, or thelike for producing a plurality of records of any transaction with aminimum amount of manipulation on the part of the operator.-v

A further object of this invention is to provide an inexpensive andself-contained mechanism for treating and folding webs of a paperparticularly adapted for usewith the above mentioned devices, by the useof which the carbon sheets heretofore required in producing manifoldcopies of a transaction are eliminated.

Other object will be in part obvious and in part pointed outhereinafter. 1

The invention accordingly consists in the several steps and the relationand order of one or more of such steps with relation to each of theothers thereof. and in the features of construction, combinations ofelements and arrangement of parts, which will be exemplified in theconstruction hereinafter set forth, and the scope of the application ofeach of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one of various possibleembodiments of this invention. Figure 1 is a partial diagrammatic viewshowing the complete apparatus; F ig. 2 is an elevational view of thefinal folding mechanisms shown at the left of Fig. l, taken at rightangles to that figure; Fig. 3 is a plan view of the first foldingmechanism shown at the right of Fig. 1;

Figs. l and 5 are detailed views respectively of opposite sldes vof theweb before the same is folded; Fig. 6 is a perspective view of atransverse section of the folded web.

Similar vreference characters refer to similar parts throughout theseveral views of the drawing. p

Referring now to the drawings in detail and more particularly Fig. l,there is denoted diagrammatically at l the mechanism or means forcoating a web of paper longitudinally in parallel sections along itsopposite sides as shown by the heavy sectioning 1n Figs. 4 and As thismay be done in any desired manner it is thought unnecessary to go intothe details of the construction of this-apparatus, the method andmaterials used in coating paper with a manifolding substance andpermitting the same to dry being old and well known in the art.

The web is then passed through printing mechanisms 2 and 3 which printupon the opposite sides of the web along the uncoated sections. Theprinted matter usually consisting of the name and address of the companyordering the .illers for its use, together with such other data, ruledlines, etc.` as may be necessary, according to the use to which they areput. The web then passes through a perforating mechanism 4 whichperforates the web longitudinally along the lines separating the coatedand printed sections. As herein shown the web is divided into foursections, although the same appatus is adapted to handle webs of threesections as will appear obvious from the description hereinafter setforth or by slight modifications it may be changed to handle a greaternumber as desired.

After being coated, printed and perforated the web is conductedtoafoldingmechanism adapted tol fold the two outer sections over uponthe two inner sections. lVhile this folding mechanism is showndiagrammatically detached from the printing 'inechanism, it is inpractice direltly connected therewith and may be considered as anattachment therefor. This folding mechanism comprises a base plate 5under which the. web is adapted to pass, the rear edge 6 of the platebeing substantially the width of the entire four sections of the web.The forward edge 7 is but one-half the width or equal to the combinedwidth of the two inlner Sections. The' outer edges lof. the web,assuming the lmachine to have been previously started and now inoperation, arev screws 14 and moving the in 15 supporting blocks 10 upor down, or tiey may be swung about a vertical axis by this same.-mecha-l nism. Set screws 16 permit the arms Sto be adjusted in thedirection of their length through the blocklO. p

' Freely suspended above the for-ward edge 7 of plate 5 by means of aflexible suspenjsion member 17 are a pairof diverging arms 18, the armsconstituting an-.inverted V-sliaped member. The edges of the web 9 passunder these arms and are `pressed .more nearly into the plane of theinner sections of the web as the same is conducted upwardly throughcreasing rollers 19. `By freely suspending the member 18 in this mannerthe tendency to tear the web if subjected to an abnormaltension islessened.

-Aftei' passing through the creasingrolll ers 1 9 the web isconductedover the adl justably mounted roller 20 and thence-over a V-shapedfolding `plate 21 whereby the web is folded along its central line ofperforations bachv .upon itself. This folding'` l plate'21 is dividedinto tw'o parts along the line 22 whereby they may be adjusted up anddown relatively to each other by means of set screws 23.- Tlius if thelweb should be feeding improperly,v that is with the line ofperforations toone lside of' the apex of the. folder 21, one side; orthe other is raised as may be necessary sothat the web is straightened,and folded exactly upon its line of perforationsasit passes through thecreasing rollers 24. At this stage the folding of the web'longitudinally in zigzag form as shownin Fig. 6 is completed. It isthen passed through continuous fold .mechanism Vfor folding-y the sametrans-A versely of itsV length into the zigzag form shown in F ig. 2.,This mechanism -which 1s of well known'style comprises substantially vtangential feed rollers 25 and 26 each hav#- ing a folder blade 27. andgrippers 28 diap metrically opposite each other controlledby lattervvcarries'the web vdown and around'. ,'throii'gha portion ,of its path oftravel, whereuponytfhe j awsrelease the .web and it v is rpermitted'ftodropfinto a `receiving box 30. ,Thel next bladethenengages; the web v means o cams'29, t-he loperation being the'engagement of theweb by thel folder blade 27 between the jawso'f thegripper 28 which the length of a printed sheet.

and the coactirig gripper jaws carry it 4.

the opposite direction downand around to produce a fold in the oppositedirection. he distance between the folds is equal to vThe web may thenbe cut by hand after the desired number of folds have been deliveredinto the receiving box 30. v

Figs. 4 and 5 denoting the` opposite sides of the web, are coated asindicatedby the heavy lines 31 and 32 upon one side `and the singlesection 33 upon the opposite side,

and are printed upon the sections 34 and 35 upon the first mentionedside and 36 'and 37 upon the other, the sect-ion 38 which f 'is the backof the under sheet being plain. As' the web is folded the sections 31and 35 are folded overl sections 34 and 32 respectively and the web issubsequently folded along the center line between thc sections 32 and 34in vthe opposite direction so that itassumes the form shown in Fig. 6with a coated surface between each pair of printed surfaces, whereby aplurality of records may be made through the manifolding materialwithout the use of separate carbon sheets, that is, the web may be feddirectly into a typewriter or recording machine and records producedwith the minimum amount of manipulation 'on the part of the operator.

While the above invention has been de-v scribed with relation to itsoperation upon a web divided into four sections, it may be operated `ina similar manner upon a web divided into three sections. In this casethe web is passed-through the same mechanism without altering it in anyway, the only difference being in passing the` web through the mechanismshown in Fig. 3, oneedge coincides with one end of the edge 6v while theopposite edge coincides with the opposite end of the edge 7. In thismanner only fone outer section is folded over on to the middle sectionof the three sections of the web. The subsequent treatment of the web issubstantially the same.

It is thus seen that this invention constitutes a lpractical and simpledevice for accomplishing, among others. all the .objects and advantagesabove set forth.

As many changes couldbe made in the above construction, and manyapparently widely different embodiments of this invention could be madewithout departing Irom the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be 'interpreted as illustrative and not in a limiting sense.
